BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. The work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

Mobile roaming may extend the coverage of a cellular network operator's services allowing a mobile user to continue using its home operator phone number, data services, and other network services while outside of a user's home network's operating region. To enable seamless coverage to mobile users while roaming to different geographic regions, a user's home network operator may have agreements in place between various visiting network operators that may address technical components of the roaming service. When a mobile user connects to a visiting network operator's network, the visiting operator may identify the mobile user's home network operator in order to determine how or if to proceed with providing network services.

DETAILED DESCRIPTION

The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. These illustrations and exemplary embodiments are presented with the understanding that the present disclosure is an exemplification of the principles of one or more inventions and is not intended to limit any one of the inventions to the embodiments illustrated. The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Among other things, the present invention may be embodied as methods or devices. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.

Network operators or providers, such as entities providing cellular phone and data service, may use various hardware, software, or other tools and systems to provide systems and methods to manage roaming configuration. Most network operators may have agreements in place with other network operators so that mobile users of each network may experience relatively seamless network access when traveling outside of a user's home network operating region. The agreements between partner network operators may include technical and financial details regarding how mobile users from each respective home network may be provided (or not provided) with services when accessing a visiting network while roaming. FIG. 1 shows a high level illustration of a roaming network 100 that may allow a user with a computing device 101 associated with a home network 110 to access network services via a visiting network 102. The computing device 101 may connect to the visiting network 102, and the visiting network operator may access a home location register 104 or similar database or directory to determine whether the computing device 101 may be associated with another network operator. In some embodiments, the visiting network operator may determine that the computing device 101 is associated with a home network operator with which the visiting network operator has a roaming agreement. In some embodiments, if the computing device is attempting to contact a computing device of another user (e.g., phone call, SMS, MMS, etc.), the visiting network 102 may route the call or message through an international transit network carrier 108 and onto the home network 110. The home network 110 may then be used to contact the call, message, or other data to a recipient computing device 112. In some embodiments, the recipient computing device 112 may be associated with another third party network provider that may be utilized to complete the network communication. In some embodiments, if the computing device is accessing data on an exterior network 106, such as the Internet, the visiting network 102 may route the computing devices 101 data request to the exterior network 106 upon determining that the visiting network operator has an agreement in place with the home network operator associated with the computing device 101. Those skilled in the art will understand that many variations of the components shown in FIG. 1 may be utilized in different embodiments, and that the roaming network 100 is merely exemplary.

An operator's home location register (HLR), such as the home location register 104 in FIG. 1, may be configured to specify roaming areas that may include/contain integrated services digital network (ISDN), mobile station ISDN (MSISDN), or visiting public land mobile network (VPLMN) identification (VPLMN-ID) for mobile users and their corresponding mobile computing devices. Traditionally, an operator's HLR may not be configured to group these identifiers in any operator specific way. Accordingly, the network operator associated with the HLR (or an administrator or application accessing the register) may not have any convenient way to determine which operator each ISDN or VPLMN-ID may be associated with. In other words, the HLR may not be traditionally configured to link particular ISDNs or VPLMN-IDs, or groups of each, with the mobile country code/mobile network code (MCCMNC) combination that may identify the mobile user's home network operator among various network operators. As a result, managing sets of ISDNs or VPLMN-IDs that belong to a specific operator may be very time consuming or substantially impossible in certain circumstances. Similarly, in systems or networks that may include a policy and charging rules function (PCRF) or policy control function (PCF) (e.g., 5G networks), the PCRF or PCF configuration may maintain individual internet protocol (IP) addresses for each computing device that connects to the network and MCCMNC values associated with the various network operators, and corresponding location and quality of service (QoS) information. Traditionally, however, the PCRF or PCF may not group the IP addresses and associated information based on each underlying computing device's home network operator.

Thus, in some embodiments, the disclosure describes a roaming configuration management system (RCMS) that may enable more efficient and streamlined roaming configuration processes. To do so, the RCMS may introduce an external abstraction of a Roaming Partner that may group ISDNs and VPLMN-IDs together that may enable improved management of a single network operator. For example, the RCMS may aggregate various network entities by type, such as global title (GT), mobile management entity (MME), MCCMNC/VPLMN-ID, access and mobility management function (AMF), session management function (SMF), and virtually any other roaming based aggregated data that may be defined by an operator and that may be configured in the network operator's systems associated with another operator or country. In some 5G networks, for example, the AMF may receive connection and session related information from the user computing device 101, and messages related to session management may be forwarded to the SMF. Further, the RCMS may allow a user to manage core network systems configuration based on the aggregated values or network entities. The RCMS may aggregate AMF/SMF values within a roaming area associated with network operators. In some embodiments, the RCMS may manage, store, and/or configure network associated IR.21 roaming partner data and information used in an operator's network. The IR.21 may be a document or repository that may include thousands of entries by various network operators. The IR.21 may also include details of mobile network operators and contain IP ranges, mobile application part (MAP) addresses, global titles, network codes, etc., for the equipment associated with each particular network operator. This information may be updated periodically, such as daily, weekly, or monthly. In some embodiments, the RCMS may help integrate the updated IR.21 information more efficiently and more quickly. In some embodiments, the RCMS may also maintain IP address ranges and associated values that may facilitate PCRF or PCF management.

In some embodiments, the RCMS may provide various external interfaces, such as a web interface for enabling administrators to update the system, and a southbound interface for access by external applications. In some embodiments, the RCMS and its interfaces may allow performance of all or most permissible roaming configuration actions within the core network elements. In some embodiments, the RCMS may also manage configuration of Roaming Dependent Service Profiles (RDSP) in the home location register/home subscriber server (HLR/HSS), which may be a custom set of rules per operator.

Accordingly, the RCMS may provide a technical solution to various technical problems. The RCMS may allow network operators to more efficiently configure and manage changes in roaming configurations while using fewer computer resources. The RCMS may allow network operators the ability to react substantially immediately (or at least more quickly) to network operator pricing changes (e.g., from roaming partners), when notified by the other network operator. Traditionally, rolling out changes to roaming configurations across an operator network could be time consuming and resource intensive (both computer and human). Thus, one practical application of the RCMS described herein may be faster and more resource efficient roaming configuration changes in response to various inputs.

In some embodiments, the RCMS may provide other technical solutions. For example, the RCMS may be a tool that may provide a centralized, web-based platform or tool for a network operator to facilitate management of global title (GT) and/or ISDN and IP ranges for other network operators (e.g., roaming partners), and/or facilitate management of the VPLMN-IDs for roaming partners. In some embodiments, the RCMS may facilitate management of the mobility management entity (MME) for LTE roaming or other types of roaming. In some embodiments, the RCMS may enable relatively rapid blocking and unblocking of roaming partners in response to circumstances related to those partners, such as partnership agreement terms, etc, and may also enable rapid blocking and unblocking of particular roaming areas as needed or desired by a network operator. In some embodiments, the RCMS may facilitate addition and removal of ISDN/GT from particularly roaming partners, and/or binding or linking roaming partners with a roaming area as a many-to-many relationship. Further, in some embodiments, the RCMS may enable backtracking of configuration changes with a history of changes completed along with comments and dates associated with those changes. Other benefits and solutions to technical problems will be evident from the disclosure.

FIG. 2 illustrates an embodiment of an exemplary computing environment 200 in which the roaming configuration management system may exist and operate. A roaming configuration management (RCM) server 202 may be in communication with or accessible by at least one or more administrator computers 204, one or more application servers 206, one or more policy and charging rules functions (PCRF) 208 (on servers or other computing environments), one or more unified subscriber directories or databases (USD) 210, and one or more provisioning gateways (PGW) 212. In some embodiments, such as those embodiments that may include 5G networks, the PGW 212 may be replaced or supplemented by an access mobility management function (AMF) and/or session management function (SMF) or a combination AMF/SMF, and the PCRF may be replace by a PCF that may be connected to and communicate with the AMF/SMF. The various connections may be made in any suitable manner known to those skilled in the art, such as fixed wire, wireless, or networked through an intranet or the internet (i.e., world wide web), or any other suitable network connection. The RCM server 202 may, in some embodiments, be specifically configured to operate the RCMS as otherwise described herein. In some embodiments, the USD 210 may also be accessible by or have access to one or more home location registers 214, as well as the PGW 212 and the PCRF 208.

In some embodiments, an RCMS-L reference point 209 may be disposed between the RCM server 202 and the USD 210. The RCMS-L reference point 209 may enable the RCM server 202 to store and retrieve data used to support the management of roaming information. In some embodiments, this roaming information may include information related to roaming partners (e.g., other network operators), roaming areas, roaming dependent services profiles, and scheduled tasks. In some embodiments, the RCMS-L reference point may be implemented in lightweight directory access protocol (LDAP), but other suitable protocols may be used within the scope of the disclosure. In some embodiments, an RCMS-P reference point 211 may be disposed between the RCM server 202 and the PGW 212. The RCMS-P reference point 211 may enable the RCM server 202 to update the HLR 214 configuration as needed or desired based on changing information related to the HRL data. In some embodiments, the RCMS-P reference point may be implemented in simple object access protocol (SOAP), but other suitable protocols may be used within the scope of the disclosure. In some embodiments, an RCMS-X reference point 207 may be disposed between the RCM server 202 and the PCRF 208. The RCMS-X reference point 207 may enable the RCM server 202 to update IP address ranges, MCCMNC value for roaming partners or other network operators, QoS references, location references, etc. In some embodiments, this information may alternatively or additionally be stored on the USD 210, but in some embodiments, this information may be stored exclusively on the PCRF 208 and not on the USD 210.

In some embodiments, the RCMS, via the RCM server 202, may provide both a web interface and a SOAP interface to facilitate managing roaming configurations for the network operator. In some embodiments, the web interface may be implemented via Hypertext Transfer Protocol Secure (HTTPS) through an HTTPS reference point 203. In some embodiments, the web interface may be accessed by administrator computers 204 of administrators associated with the network operator. The SOAP interface may be implemented through a SOAP reference point 205. In some embodiments, the SOAP interface may be accessed by other applications housed on other application servers 206.

In some embodiments, the RCM server 202, via both the web interface and the SOAP interfaces, may provide users with the ability to perform a variety of functions in the following non-limiting list:

-   -   Whitelist and/or blacklist a roaming area.     -   Add a new roaming partner and/or delete a roaming partner.     -   Block and/or unblock a roaming partner.     -   Assign a roaming partner a default location reference.     -   Assign a roaming partner a default QoS.     -   Assign QoS or location reference to a roaming partner's MCC/MNC         or IP address range.     -   Unassign QoS or location reference from roaming partner's         MCC/MNC or IP address range.     -   Add and/or remove IP address range (either IPv4 or IPv6) for a         roaming partner (may include optional QoS and location         reference).     -   Add and/or remove a MCC value for a roaming partner.     -   Add and/or remove an MNC value for a roaming partner.     -   Add and/or remove a country code (CC) value for a roaming         partner.     -   Add and/or remove a network destination code (NDC) value for a         roaming partner.     -   Add and/or remove a VPMLN-ID or ISDN for a roaming partner.     -   Add and/or remove MME Address for a roaming partner.     -   Add and/or remove a MME roaming area.     -   Block and/or unblock a MME roaming area.     -   Associate and/or disassociate a roaming partner with an MME         roaming area.     -   Add and/or delete a roaming area.     -   Block and/or Unblock a roaming area.     -   Associate and/or disassociate a roaming partner with a roaming         area.     -   Create and/or delete a roaming subscription.     -   Create, modify, and/or delete a roam plan information entry.     -   Create, modify, and/or delete a roam plan.     -   Create, modify, and/or delete any of four roam entries         specifying roaming treatments:         -   Basic service;         -   Supplementary service;         -   Operator determined barring (ODB) related; and         -   Customized Application for Mobile networks Enhanced Logic             (CAMEL) related.     -   Register and/or unregister a roaming partner with a roaming         subscription.     -   Search for entries associated with a QoS or location reference         (locRef) values.     -   Locate roaming plans by searching for complete or partial names         or for plans that use named treatments.     -   Display a history of changes made to roaming management         configurations.

In some embodiments, the functionalities in the below non-limiting list may only be available via the web interface, or through both the web interface and SOAP interfaces in other embodiments:

-   -   Mobile Country Code (MCC) management:         -   Ability to create, modify and delete MCCs, and/or ability to             search for MCCs based on country name.     -   Locate roaming partner information by searching for complete or         incomplete values of Name, MCC, MNC, CC, NDC, IP address, QoS,         location reference. In some embodiments, the interface may         provide for selecting which roaming partner information is         displayed in a summary, chosen from all roaming partner values.         In some embodiments, the interface may provide for selecting any         roaming partner entry and displaying complete information for         that roaming partner.     -   Search an identified roaming partner for an ISDN or VPMLN-ID         (partial or complete).     -   Locate roaming areas by searching for complete or partial names,         with results displaying the list of associated ISDNs and/or         VPLMN-IDs, and whether the geographic area is blacklisted or         whitelisted.

In some embodiments, the abstraction of Roaming Partner may refer to a name given to a single or group of MCC-MNC combinations. In some embodiments of the RCMS, each roaming partner may have the following non-exclusive list of properties:

-   -   At least one mobile country code (MCC).     -   A set of mobile network codes (MNCs) per MCC.     -   At least one country code (CC).     -   A set of network destination codes (NDCs) per CC.     -   A set of ISDNs.     -   A set of VPLMN-IDs.     -   A set of associated roaming subscription plans.     -   A default standard roaming plan.     -   A default routing roaming plan.

FIG. 3 shows an embodiment of a data structure or data tree 300 that may be used to represent a roaming partner 302. The roaming partner 302 data may be identified and grouped in any of the GPRS 304, EPS 306, or PCRF 308 domains. Under GPRS 304 (e.g., GSM networks), each roaming partner may be associated with quality of service (QoS) 310 data that may applicable to users under the particular roaming partner's network. The MCCMNC 312 is a combination of a mobile country code (MCC) and a mobile network code (MNC), and may include a unique combination of values that identifies the network operator name. In other words, in some embodiments, the MCCMNC 312 may only be associated with one roaming partner. In some embodiments, checks may be made or automated to ensure that duplicate MCCMNCs are not created across multiple roaming partners. It may, however, be possible for a roaming partner to have multiple MNCs (mobile network codes) associated with that particular roaming partner. In some embodiments, the MCC may include three decimal digits and the MNC may include two or three decimal digits (e.g., an MNC of 001 is not the same as MNC of 01). In some embodiments, the first digit of the mobile country code may identify a geographic region as follows, where the digits 1 and 8 are not used:

-   -   0—Test networks     -   2—Europe     -   3—North America and the Caribbean     -   4—Asia and the Middle East     -   5—Australia and Oceania     -   6—Africa     -   7—South and Central America     -   9—Worldwide (e.g., satellite, aboard aircraft, maritime,         Antarctica)         In some embodiments, an MCC may be used in combination with an         MNC to uniquely identify a network operator using the GSM, UMTS,         LTE, 5G, CDMA, or other public land mobile networks. In some         embodiments, a roaming partner 302 may be associated with         multiple MCCMNCs due to the possibility that a roaming partner         may have multiple MNCs associated with it. Accordingly, each         MCCMNC 312 associated with the roaming partner 302 may include a         list of global titles (GT) associated with a particular MCCMNC.         For example, FIG. 3 shows a roaming partner that includes three         MCCMNCs with associated lists of GTs: MCCMNC 1 (314A) associated         with list of GT 316A, MCCMNC 2 (314B) associated with list of GT         316B, and MCCMNC 3 (314C) associated with list of GT 316C,         although more or few MCCMNCs may be used per roaming partner. A         global title may be an address used for routing signaling         messages on the network. In some embodiments, the global title         may be a unique address which refers to only one destination         (e.g., user computing device).

Under the EPS (evolved packet system) 306 domain (e.g., LTE networks), a VPLM-ID 318 may be substantially the equivalent to the MCCMNC in the GPRS domain and associated with an mobility management entity (MME) 320. Similarly, the VPLMN-ID 318 may be associated with only one roaming partner. In some embodiments, the MME 320 may be a control node for the LTE network and may be responsible for idle mode user equipment paging and tagging procedure, including retransmissions. The MME 320 may also be responsible for authenticating users (e.g., by interacting with the HSS). In some embodiments, ISDN may be a number provided as a range of ISDN or just one ISDN for a particular roaming partner. In some embodiments, in the GPRS 304 domain (e.g., for 2G and 3G networks), the ISDN or range of ISDNs may be referred to.

The PCRF 308 may provision IP or IP ranges related roaming partners and assign QoS and Location Reference (LocRef) at the roaming partner level and/or at each IP level. Each roaming partner 302 may have a PCRF QoS Default 322 as a default quality of service for that roaming partner, and a default location reference 324, The PCRF 308 may also include data for multiple MCCMNCs for a particular roaming partner such as MCCMNC 1 (326A), MCCMNC 2 (326B), MCCMNC 3 (326C). In some embodiments, IP ranges associated with the roaming partner for a particular MCCMNC may be expressed as IP Range/32. Each MCCMNC or IP Range may also include location refs 328A, 328B, and 328C, respectively, as well as quality of service data 330A, 330B, and 330C, respectively. In some embodiments, the IP range may also include the individual IPs 332A, 332B, and 332C for each IP range. In some embodiments, the RCMS user or admin may provide IP ranges in a subnet format via an interface and the RCMS tool may internally store individual IP and may allow changing location references and QoS references (locref and qosref) for each individual IP. In some embodiments, the locref and qosref for each IP may be stored in a mapping table. In some embodiments, a user or admin may search a single IP or range associated with a roaming partner across all roaming partners. In some embodiments, duplicate IPs may not be supported and the RCMS may support IPV4 and IPV6 ranges.

In some embodiments, the location reference or “locref” may be specific to the PCRF 308, and may be stored (or additionally stored) at the PCRF, such as PCRF 208 in FIG. 2. In some embodiments, the RCM server 202 may receive a distinct list of locref values to be stored as a master list for use with the RCMS. In some embodiments, the locref field may be associated at the roaming partner level, at the IP range level, or even at a specific IP level. In some embodiments, a user or admin accessing the RCMS may choose a locref value from the master list to be applied on the roaming partner, IP range, or specific IP level. In some embodiments, when the RCM server 202 or the RCMS is updated (using a sync tool or other data update), the locref values from the PCRF 208 may be retrieved and may override the entries stored on the RCM server 202 or an RCMS database associated with the RCMS. Thus, the locref values may be made to be synchronized across the RCM server 202 and the PCRF 208. In some embodiments, an admin or other authorized user may create new roaming partners with new associated location references that may be entered into the PCRF 208 to add to the master list. In some embodiments, a new roaming partner may be added an existing location reference, and multiple roaming partners may be associated with one location reference. In some embodiments, a roaming partner may be removed from a location reference. In some embodiments, cross-checks may be in place to avoid or limit the ability to remove a location reference from the RCMS if the location reference Is mapped to any of the roaming partners. In some embodiments, when a new roaming partner is being created, the accessible roaming locations and descriptions may be available on the RCMS interface in a drop down list, for example, for single selection.

In some embodiments, the single selection during set up of a new roaming partner may become the default location reference for the roaming partner, such as default loc ref 324 for the roaming partner 302 in FIG. 3. In some embodiments, when an MCCMNC or IP Address/Range is added to a roaming partner (e.g., MCCMNC 1 326A in FIG. 3), a different location reference may be defined to the MCCMNC or IP Address/Range than the default location reference for that roaming partner, the default location reference may be overridden for that specific entry. In some embodiments, if the default location reference is changed for a roaming partner, then the location references that may be the same for the previous default (e.g., not previously overridden) may be changed to the new default location reference. In some embodiments, if the user or administrator wants to update all location references associated with a particular roaming partner to match a new default location reference value, the RCMS interface may include a confirmation inquiry, such as a pop-up question, to be selected to confirm the override. In some embodiments, a previous number of location states (e.g., the previous three location reference values) may be stored in the RCM server 202 along with dates of change for each roaming partner or sub-entry associated with the roaming partner. In some embodiments, the RCMS interface may enable a user to search for one or all or a subset of entries associated with a roaming partner or location reference.

In some embodiments, the QoS reference or “qosref” value may be specific to the PCRF 308, and may be stored (or additionally stored) at the PCRF, such as PCRF 208 in FIG. 2. In some embodiments, the RCM server 202 may receive a distinct list of qoscref values to be stored as a master list for use with the RCMS. In some embodiments, the qosref field may be associated at the roaming partner level, at the IP range level, or even at a specific IP level. In some embodiments, the PCRF QoS default 322 may be assigned by default to all members of the MCCMNC in the PCRF. In some embodiments, when the RCM server 202 or the RCMS is updated (using a sync tool or other data update), the qosref values from the PCRF 208 may be retrieved and may override the entries stored on the RCM server 202 or an RCMS database associated with the RCMS. Thus, the qosref values may be made to be synchronized across the RCM server 202 and the PCRF 208.

In some embodiments, the default QoS may be overridden for a roaming partner, which may change qosref values for those values that have not been previously overridden with non-default values. In some embodiments, if the user or administrator wants to update all qosref values associated with a particular roaming partner to match a new default qosref value, the RCMS interface may include a confirmation inquiry, such as a pop-up question, to be selected to confirm the override. In some embodiments, different qosref values may be assigned to a MCCMNC or IP ranges associated with a roaming partner in the PCRF 208. In some embodiments, if a new IP entry, IP range, or MCCMNC may be added to the PCRF 208 or RCMS database under a particular roaming partner and the QoS is not specifically defined, the QoS default 322 associated with the particular roaming partner 302 may be assigned. The default qosref value may subsequently be changed for an MCCMNC or IP range, or specific IP. In some embodiments, a previous number of qosref states (e.g., the previous three qosref values) may be stored in the RCM server 202 along with dates of change for each roaming partner or sub-entry associated with the roaming partner. In some embodiments, the RCMS interface may enable a user to search for one or all or a subset of entries associated with a roaming partner or qosref value.

In some embodiments, the locref and qosref values for each entity may be stored at the PCRF 208 in a mapping table. Table 1 may be an example of a mapping table stored on a PCRF:

TABLE 1 MCCMNC1 locref qosref MCCMNC2 locref qosref MCCMNC3 locref qosref

In some embodiments, an entry of a new or existing roaming partner may become invalid if an already-mapped MCCMNC or ISDN or VPLMN-ID with one another. Table 2 shows examples of combinations of MCCMNC and ISDN values that may render a roaming partner entry invalid:

TABLE 2 Roaming Partner 1 MCCMNC1 ISDN1 Valid Roaming Partner 1 MCCMNC1 ISDN2 Valid Roaming Partner 1 MCCMNC2 ISDN1 Invalid Roaming Partner 2 MCCMNC3 ISDN1 Invalid Roaming Partner 2 MCCMNC1 ISDN4 Invalid In Table 2, for example, a Roaming Partner 1 entry may become invalid when already-mapped ISDN1 is paired with MCCMNC2. Similarly, a Roaming Partner 2 entry may become invalid when already mapped ISDN1 is paired with MCCMNC3, or when ISDN4 is paired with already-mapped MCCMNC1. Of course, those skilled in the art will recognize that the relationships in Table 2 are for illustration purposes only.

In some embodiments, the RCMS may include certain high level operation sequences. For example, it may be desirable to sync roaming partner and roaming area configuration in the RCM server 202 or RCMS database from other corresponding environments before any operations. In some embodiments, an admin accessing the RCM server via RCMS interface may access individual PGW 212, PCRF 208, or AMF/SMF systems to update roaming area or roaming partner configuration, so syncing may be desirable to make sure the corresponding RCMS database values are updated. Backups may be created to facilitate rollbacks in case of errors. In some embodiments, one possible operation sequence may be sync, apply operation, and rollback (in case of failure). In some embodiments, the sync process may be defined as follows:

-   -   Obtain the latest roaming configuration, such as from the PGW         212 or AMF/SMF;     -   Take backup of PGW configuration and RCMS equivalent data of the         same entity;     -   Compare PGW configuration data with the current configuration         data in the RCMS database;     -   If no problems, apply the change in the RCMS database to match         the PGW configuration data; or     -   If conflicts, cancel the operation and make sure RCMS         configuration was not changed.

In some embodiments, changes in roaming configuration made using the RCMS interface or otherwise through the RCM server 202 may be scheduled as a job. In some embodiments, the user or administrator requesting the changes may schedule a particular date and time for the changes to apply in the respective system. Once requested, the RCMS may review the scheduled jobs and may reject or approve the change request based on certain predetermined criteria. Once a particular job is scheduled and approved, the job may proceed and may be successful or may fail. In some embodiments, if all the requested changes to the roaming configuration were applied successfully, the status of that job may be changed to “pass.” If errors occur during any phase of the operation sequence (such as the operation sequence listed above), the job status may be changed to “fail.” In some embodiments, if a requested job is not approved by a particularly predetermined time or by that job's scheduled time, the RCMS may provide for the admin or user who requested the job to resubmit the job with a new date and time.

In some embodiments, particularly in embodiments that may include 5G networks, the roaming configuration changes or updates may be applied so as accommodate network slice management. Network slicing may be used in some embodiments to accommodate varying QoS requirements for varying types of uses and users on the same network infrastructure. To the extent that roaming configuration may include changes to the QoS or other service level requirements (SLA) involve in network slice management, the RCMS may be implemented to deploy changes or updates to that configuration. In some embodiments, the RCM server may include or may communicate with a network slice controller to manage roaming configuration across 5G networks.

The RCMS interface, either via the HTTPS reference point 203 or the SOAP reference point 205 may, include a graphical user interface (GUI) including data related to configuration information in varying formats. FIGS. 4A, 4B, 4C, 4D, and 4E show examples of exemplary layouts and screens of the RCMS interface 400. In some embodiments, the RCMS interface 400 may include at least a data selection portion 402 and a data configuration portion 403. The data selection portion 402 may include options to select from one or more data display and configuration options such as Manage Partners 404, Manage Countries 406, Manage Areas 408, Manage RDSP 410, Manage Scheduler 412. FIG. 4A shows an example of the RCMS interface 400 with the manage partners 404 data selection selected. In some embodiments, the Manage Partners 404 selection may show data in a column for all roaming partners 414 for the particular network operator. For each roaming partner, the data configuration portion 403 may indicate the country name 416 for that roaming partner, the “blocked status” 418 of the particular roaming partner (e.g., blocked or unblocked), and status selections 420 to select whether the status of a roaming partner should be blocked, unblocked, or another option. In some embodiments, the RCMS interface 400 may further include search options for each data column. For example, a user searching for data to manage a particular roaming partner may enter that roaming partner's name into the search box in the partner name 414 to show country name and blocked status for the identified partner. In some embodiments, the data configuration portion 403 of the Manage Partners 404 selection may include an Add New Partner button 422 that may be selected of a user would like to add a new roaming partner to the database.
